Subject: zynqmp: dts: Cleanup no-1-8-v property from sdhci dt nodes
X-Git-Tag: v2020.04-rc1~20^2~12
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=166fb46ad3ca9ab98e5bc450fbb1031949c1b091;p=oweals%2Fu-boot.git

zynqmp: dts: Cleanup no-1-8-v property from sdhci dt nodes

Removed no-1-8-v property from zynqmp sdhci devicetree nodes to
allow UHS-I capable SD cards to work in SD3.0 UHS modes.

Boards that does not have level shifter for SD, does not support 1.8v.
so no-1-8-v property to sdhci dt nodes should be present in zcu102 Rev-A,B,
zcu104 Rev-A,C, zcu100, zcu1275 Rev-B boards.
